In particular, methods of displaying and communicating a desired target flow rate and cardiac index during cardiopulmonary bypass surgeries are provided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of graphically displaying target blood flow rate on a display screen of a user interface during cardiopulmonary bypass surgery, the method comprising the steps of: providing patient data including height, weight, and a desired cardiac index to the user interface; displaying a first graphical indicator of actual blood flow rate in real time on the display screen; calculating target blood flow rate with a processing component associated with the user interface, wherein the target blood flow rate is at least partially based on the patient data; and displaying a second graphical indicator of the calculated target blood flow rate on the display screen.
2. The method of claim 1 , further comprising displaying a numerical value of an actual cardiac index in real time on the display screen.
3. The method of claim 1 , further comprising displaying a numerical value of actual blood flow rate in real time on the display screen.
4. The method of claim 1 , wherein the step of displaying a second graphical indicator of the calculated target blood flow rate on the display screen comprises overlaying the second graphical on the first graphical indicator.
5. The method of claim 1 , wherein the step of displaying a second graphical indicator of the calculated target blood flow rate on the display screen comprises displaying a vertical green bar on the display screen.
6. The method of claim 1 , wherein the step of providing patient data to the user interface comprises displaying a settings screen and entering the patient data into the settings screen.
7. The method of claim 6 , further comprising selecting a body surface area algorithm from the settings screen.
8. The method of claim 7 , wherein the patient data further comprises the selected body surface algorithm.
